Impact of bioregulator on corn resilience to non-optimal temperatures

Abstract

A plant’s ability to maintain productivity under extreme temperatures and drought depends on its genotype and stress response. Therefore, current research focuses on identifying corn lines and hybrids with high germination energy and vigor in cold soils, as well as stable growth under drought and temperature fluctuations. Their performance can be improved through an integrated approach combining genetic potential with pre-sowing seed treatment using natural growth regulators. The aim of this study was to evaluate the effect of the bioregulator JS, extracted from Juniperus sabina L. plant, on the early stages of seed development of the mid-season corn hybrid Porumbeni 396 MRf (FAO 390) under temperature stress.
